Doing a bit better, thank you.
It would appear that a couple of things may be questionable. Your route map on line 226 appears to refer to an access list 130 that isn't in the config, and list 150 only applies to the 192.168.16.0/24 network as the only one allowed to use the overload nat via the negotiated Dialer 0 address.
Also, your named access list applied to vlan doesn't appear to allow web traffic to public ip addresses.
Are you trying to route the xp machine directly out to the internet or through a proxy?
